A dual, preferably orthogonally polarized microstrip patch antenna which includes a layer of electrically insulating material in the form of a printed circuit board. First and second sets of electrically conductive patches, preferably of copper, are disposed on one surface of the electrically insulating material, the first set adapted for transmission and/or reception of electromagnetic radiations polarized in a first direction and the second set adapted for transmission and/or reception of electromagnetic radiations polarized in a second direction. Patches of the first set are interlaced with patches of the second set. A feed for each of the patches is coupled to the opposing surface of the electrically insulating material which includes a first plurality of slots, one associated with each of the patches of the first set for polarizing the patches of the first set in the first direction and a second plurality of slots, one associated with each of the patches of the second set for polarizing the patches of the second set in the second direction. The centers of the patches of the first and second sets of patches are disposed in a straight line and the centers of adjacent patches of each of the sets of patches are spaced apart less than one wavelength of the carrier frequency of interest.

[ We claim:] [1.] An antenna which comprises:(a) a substrate of electrically insulating material having first and second surfaces on opposite sides thereof;(b) a first set and a second set of electrically conductive patches disposed on said first surface of said electrically insulating material, said patches of said first set being adapted for transmission and/or reception of electromagnetic radiations polarized in a first direction and said patches of said second set being adapted for transmission and/or reception of electromagnetic radiations polarized in a second direction which is different from said first direction, said patches of said first set being alternatingly interleaved with said patches of said second set such that said patches of said first and second sets together form a single column of patches, and (c) a feed arrangement provided on said second surface of said electrically insulating material and associated with said patches of said first and second sets, said feed arrangement including a first feed which is operatively coupled to one of said patches of said first set, and a second feed which is operatively coupled to one of said patches of said second set, said second feed being electrically separate from said first feed.
